摘要:
Systems and techniques are presented for determining the position of a mobile device. The mobile device receives two beacon packets transmitted at varying power levels by a first beacon and determines received signal strength (RSS) levels for the beacon packets. A maximum distance and a minimum distance are determined based on the power levels that the packets were transmitted at and the RSS levels that the packets were received at. An area around the first beacon is determined based on the distance range. The mobile device receives two additional beacon packets transmitted at varying power levels by a second beacon and determines RSS levels for the beacon packets. A distance range between the mobile device and the second beacon is determined and an area around the second beacon is determined based on the distance range. The area of overlap between the beacons is where the mobile device is positioned.

This disclosure describes processes and methods for enhancing reporting of status information in a wireless sensor network. This disclosure also provides designs of wireless sensor devices configured to connect to a wireless network, and to execute the processes disclosed herein. As described herein, a first sensor device transmits a beacon signal to a second wireless device, and the beacon signal is transmitted while the first and second wireless devices are disconnected from the sensor network. The first wireless device facilitates supplemental network formation by transmitting information to the second wireless device, wherein the information causes the second wireless device to form the supplemental network by performing network joining procedures with the first wireless sensor device, and wherein, after performing network joining procedures, the second wireless device transmits status information to the first wireless sensor device. The first wireless device then connects to the wireless network and transmits the status information through the network.
摘要:
A communication link is established between the smart card and a computer using a valid smart card communication protocol. A smart card communication device determines the valid smart card communication protocol used by a smart card by polling a communication channel using a plurality of smart card communication protocols until a valid acknowledgement message is received. A radio frequency circuit is configured to communicate with the smart card using the valid smart card communication protocol. A digital signal processor having at least two demodulators demodulates an incoming data stream produced by the receiver in accordance with the valid smart card communication protocol in a dynamically reconfigurable manner.

Computer-based systems provide a wireless, high fidelity, real-time video and audio immersive environment for multiple users. A user may be equipped with a head mounted display device which wirelessly receives real-time video signals transmitted by a radio transceiver linked to a computer that generates the real-time video images. Aspects include body, arm and leg motion and orientation sensors in wireless communication with a radio transceiver linked with a computer. Video images may be generated using a portable array of user dedicated computers controlled by a single computer that is controlled by an operator.

A method for determining a status of transit media where the method includes imaging transit media with an optical imager to create a digital image of one or more surfaces of transit media. The method includes generating optical data from the digital image. Optical data includes information indicative of a transit product or usage. The method includes obtaining magnetic data from a magnetic strip of transit media with a magnetic media reader. Magnetic data includes information indicative of the transit product or usage encoded within the magnetic strip. Some embodiments include comparing, using a processing unit, optical data with magnetic data to determine whether optical data corresponds with magnetic data. The method can involve implementing one or more business rules from a database of business rules. This implementation can be based on the comparison. The method includes determining a status of transit media based on the implementation of business rules.

Disclosed is a modular, expandable, and portable shooting range system and method of installation. The system can include one or more shooting modules that mount together to provide different numbers of shooting lanes with various lengths. The shooting modules are pre-engineered with removable panels to permit additional shooting modules to be added on as customer orders. This configuration also permits adding to the length of the shooting range to accommodate firing of different weapons. The shooting range system can further include a control booth which is divided from the shooting lanes. The control booth can be integrally formed with the shooting modules, or can be separate. The control booth can include a module control which allows a person to control lighting, air, and target control systems of the shooting range system, and can further provide a safe location to view the range.

Embodiments of systems, methods, and machine-readable media are disclosed for enabling the management of a transit user account of a transit system with a mobile device. Embodiments of a transit system utilizing such transit user accounts are also disclosed. Embodiments for enabling a mobile device to manage a transit user account can include receiving an identification code of a fare media and receiving contact information of the mobile device. The transit user account, which can be used in transactions of the transit system associated with the fare media, can be created using user information and a passcode. Additionally, the mobile device can be authenticated by sending at least one message to the mobile device and receiving at least one message from the mobile device.
